论文摘要
作为Metaversa的关键技术,无线最终扩展现实(XR)吸引了行业和学术界的广泛关注。但是,严格的延迟和超高数据速率要求阻碍了无线最终XR的发展。语义通信不是通过逐步传输原始源数据,而是关注源中包含的语义信息的成功传递,这些语义信息在减少无线系统的数据流量方面表现出了巨大的潜力。受语义通信的启发,本文为无线Ultimate XR开发了一个联合语义传感,渲染和通信框架。特别是,语义传感用于通过探索语义信息的时空分布来提高感应效率。语义渲染旨在降低语义上冗余像素的成本。接下来,采用语义通信来用于无线Ultimate XR的高数据传输效率。然后,提供了两个案例研究以证明所提出的框架的有效性。最后,确定了潜在的研究方向,以增强语义意识无线最终XR的发展。
As a key technology in metaversa, wireless ultimate extended reality (XR) has attracted extensive attentions from both industry and academia. However, the stringent latency and ultra-high data rates requirements have hindered the development of wireless ultimate XR. Instead of transmitting the original source data bit-by-bit, semantic communications focus on the successful delivery of semantic information contained in the source, which have shown great potentials in reducing the data traffic of wireless systems. Inspired by semantic communications, this article develops a joint semantic sensing, rendering, and communication framework for wireless ultimate XR. In particular, semantic sensing is used to improve the sensing efficiency by exploring the spatial-temporal distributions of semantic information. Semantic rendering is designed to reduce the costs on semantically-redundant pixels. Next, semantic communications are adopted for high data transmission efficiency in wireless ultimate XR. Then, two case studies are provided to demonstrate the effectiveness of the proposed framework. Finally, potential research directions are identified to boost the development of semantic-aware wireless ultimate XR.
